[PATCH v11 01/20] gpu: nova-core: gsp: Return GspStaticInfo from boot()

Joel Fernandes

Refactor the GSP boot function to return GetGspStaticInfoReply.

This enables access required for memory management initialization to:
- bar1_pde_base: BAR1 page directory base.
- bar2_pde_base: BAR2 page directory base.
- usable memory regions in video memory.
